Questions About Z83.0Overview
Is Z83.0 (Family history of other specific disorders) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report family history of human immunodeficiency virus [HIV] disease on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
Can Z83.0 be a principal diagnosis?
No. The Medicare Code Editor rejects this code as a principal diagnosis because family history of human immunodeficiency virus [HIV] disease describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.
Is Z83.0 exempt from POA reporting?
Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for family history of human immunodeficiency virus [HIV] disease on inpatient claims.
What is the ICD-9 equivalent of Z83.0?
Under the General Equivalence Mappings, family history of human immunodeficiency virus [HIV] disease converts to ICD-9-CM V19.8 (family hx-condition NEC). The mapping is approximate, so confirm the match fits the documentation.
